Substitute Part Grouping Explanation

Substitution of the LP122M200H5P3 is determined by strict adherence to the following electrical and mechanical parameters:

Electrical Equivalence Requirements:

Capacitance: 1200 µF (exact match)
Voltage Rating: 200 V (exact match)
Tolerance: ±20% (exact match)
Operating Temperature: -40°C ~ 105°C (exact match)
Polarization: Polar (exact match)

Mechanical Compatibility Requirements:

Mounting Type: Through Hole (exact match)
Package / Case: Radial, Can - Snap-In (exact match)
Lead Spacing: 0.394" (10.00mm) (exact match)

Compliance Requirements:

RoHS3 Compliant (all substitutes must maintain compliance)
REACH Unaffected (all substitutes maintain status)

All identified substitute parts meet these core requirements. Variations in ESR (Equivalent Series Resistance), ripple current ratings, and operational lifetime at temperature represent secondary performance characteristics that do not preclude substitution but indicate enhanced or alternative performance profiles suitable for specific application demands.

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and full RoHS3 compliance, ensuring continued availability and regulatory conformance. Selection among substitute options is determined by dimensional constraints and operational lifetime requirements specific to the application circuit.

381LQ122M200J052: This substitute provides extended operational lifetime (2000 Hrs @ 105°C) compared to the main part (1000 Hrs @ 105°C) with comparable ESR performance (166mOhm @ 120Hz). The reduced diameter (0.984" / 25.00mm) and increased height (2.047" / 52.00mm) require verification of available board space. This configuration is suitable for applications with space constraints in the radial direction.

381LQ122M200K032: This substitute offers extended operational lifetime (2000 Hrs @ 105°C) with intermediate dimensional profile (1.181" diameter / 30.00mm, 1.457" height / 37.00mm). ESR performance matches the 381LQ122M200J052 variant (166mOhm @ 120Hz). This option provides balanced performance and dimensional compatibility for most retrofit applications.

381LX122M200K042: This substitute provides the highest operational lifetime (3000 Hrs @ 105°C) with intermediate dimensional profile (1.181" diameter / 30.00mm, 1.654" height / 42.00mm). ESR specification is not provided for this variant. Selection of this part requires confirmation that ESR performance is acceptable for the application.

381LX122M200K052: This substitute provides the highest operational lifetime (3000 Hrs @ 105°C) with comparable ESR performance (166mOhm @ 120Hz). The dimensional profile (1.181" diameter / 30.00mm, 2.047" height / 52.00mm) requires verification of available axial board space. This configuration is suitable for applications prioritizing extended operational life with space availability in the axial direction.

Frequently Asked Questions (FAQ)

Q: Can the LP122M200H5P3 be directly replaced with any of the listed substitute parts?

A: Direct replacement is possible only when the application circuit accommodates the dimensional variations of the substitute part. All substitutes maintain identical electrical specifications (1200 µF, 200 V, ±20% tolerance) and identical lead spacing (0.394" / 10.00mm). Verification of available board space in both radial and axial directions is required before substitution.

Q: What is the significance of the different operational lifetimes (1000 Hrs, 2000 Hrs, 3000 Hrs @ 105°C)?

A: Operational lifetime at elevated temperature indicates the expected service duration under continuous operation at 105°C. The main part (LP122M200H5P3) specifies 1000 Hrs, while substitute parts offer extended lifetimes of 2000 Hrs or 3000 Hrs. Selection depends on the application's thermal environment and required service life. Extended lifetime does not alter electrical performance but indicates enhanced internal construction.

Q: Are there dimensional restrictions that prevent substitution?

A: Yes. The main part has a diameter of 1.378" (35.00mm) and height of 1.378" (35.00mm). Substitute parts vary in both dimensions. The 381LQ122M200J052 has the smallest diameter (0.984" / 25.00mm) but the largest height (2.047" / 52.00mm). The 381LQ122M200K032 and 381LX series parts have intermediate dimensions. Board layout must accommodate the specific dimensional profile of the selected substitute.

Q: What does ESR (Equivalent Series Resistance) represent, and why does one substitute lack this specification?

A: ESR is the internal resistance of the capacitor at a specified frequency (120Hz in this case). Lower ESR indicates better high-frequency performance and reduced heat generation. The main part and most substitutes specify 165-166mOhm @ 120Hz. The 381LX122M200K042 does not provide ESR specification in the available data. Confirmation of ESR performance is required if this part is selected for applications sensitive to impedance characteristics.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use identical Through Hole mounting with Radial, Can - Snap-In package configuration and 0.394" (10.00mm) lead spacing. Packaging format is consistent across all options. Inventory availability varies: 381LX122M200K052 has the highest stock (3216 Pcs), while 381LX122M200K042 has the lowest (1045 Pcs).

Q: Do substitute parts maintain the same compliance certifications?

A: Yes. All substitute parts are RoHS3 compliant and REACH unaffected, matching the compliance status of the main part LP122M200H5P3. Regulatory conformance is maintained across all substitution options.
